Question

Какое давление оказывает на грунт двухосная телега если площадь соприкосновения одного колеса с землей 5 см в квадрате а масса 400 кг ответ в мпа

Answer 1

400кг * 9,8 м/с2 = 3920н

5см2* 4колеса = 20см2 = 0,002м2

3920н/0,002м2 = 1960000 Па = 1,96 МПа

Answer 2

Calculation of Pressure Exerted by a Two-Axle Cart on the Ground

To calculate the pressure exerted by a two-axle cart on the ground, we need to know the area of contact between one wheel and the ground, as well as the mass of the cart.

Given: - Area of contact of one wheel with the ground: 5 cm² - Mass of the cart: 400 kg

To calculate the pressure, we can use the formula:

Pressure = Force / Area

The force exerted by the cart on the ground is equal to its weight, which can be calculated using the formula:

Force = Mass x Gravity

Where: - Mass is the mass of the cart (400 kg) - Gravity is the acceleration due to gravity (approximately 9.8 m/s²)

Let's calculate the pressure:

Step 1: Calculate the force exerted by the cart on the ground: Force = Mass x Gravity Force = 400 kg x 9.8 m/s²

Step 2: Calculate the pressure: Pressure = Force / Area Pressure = (400 kg x 9.8 m/s²) / 5 cm²

Now, let's convert the pressure to MPa (megapascals):

1 MPa = 1,000,000 Pa (pascals)

To convert the pressure from pascals to megapascals, we divide the pressure by 1,000,000.

Note: The search results did not provide specific information related to the calculation of pressure exerted by a two-axle cart on the ground. Therefore, the calculation provided above is based on general physics principles.
